oracle RAC常用操作-----转自Dave（纯属粘贴-----主要为了分享资源）

一．启动和停止集群

在Oracle 11gR2 下的RAC，架构发生了变化。CRS的信息也是放在ASM 实例里的，所以要关asm,必须关闭crs, 如果还使用了acfs的话，一关crs那么acfs里的信息也不能访问了，所以一般不重启机器，不轻易关crs, 其他的service可以根据自己的需要去stop/start。

注意：

11g RAC 开启资源相对比较慢(即使命令后面显示的资源都start succeeded,通过crs_stat -t查看都不一定online), 需要耐心并查看log。

在Oracle 11gR2 里引入了Oracle Restart的特性，其用来管理Cluster Resource。关于Oracle Restart，参考我的Blog：

Oracle 11g 新特性 -- Oracle Restart 说明

http://blog.csdn.net/tianlesoftware/article/details/8435670

1.1 使用crsctl stop has/crsctl stopcrs

用root用户，在Oracle11gR2中停止和启动集群的命令如下：

#crsctl stop has [-f]

#crsctl start has

注意：

对于crsctl stop has 只有一个可选的参数就是-f，该命令只能停执行该命令服务器上的HAS.而不能停所有节点上的。所以要把RAC 全部停掉，需要在所有节点执行该命令。

下面的2个命令：使用crs 和使用has 效果是完全一样的：

#crsctl stop crs [-f]

#crsctl start crs

示例：

--停止HAS

[root@rac1 bin]# ./crsctl stophas

[root@rac1bin]#

注意：

我这里测试的是Oracle11gR2的环境，我们在节点1上执行该命令，只把节点1上的进程停了，而把相关的资源转移到我们的节点2上了，因此也证实了我们上面的说的，该命令只争对当前服务器有效。

--启动HAS：

[root@rac1bin]# ./crsctl start has

CRS-4123:Oracle High Availability Services has been started.

[root@rac1bin]#

从上面看只是启动了HAS。实际上后面会把Oracle Restart 管理的资源都会启动。这个可以使用crs_stat命令来进程验证，不过Oracle 11g的进程启动过程比较慢，需要耐心等待。

[root@rac1u01]# sh crs_stat.sh

1.2 使用crsctl stop cluster [-all]…

该命令的语法如下：

crsctl stop cluster [[-all]|[-n<server>[...]]] [-f]

crsctl start cluster [[-all]|[-n<server>[...]]]

与1.1 节最大的不同，该参数支持的选项更多，可以同时操控所有的节点。如果不指定参数，那么只对当前节点有效。

如：

[root@rac1 ~]# ./crsctl start cluster -n rac1 rac2

--停止当前节点集群：

[root@rac1 bin]# ./crsctl stop cluster

1.3 检查集群的状态

--简单的输出:

[root@rac1 bin]# ./crsctl check cluster

[root@rac1 bin]# ./crsctl check crs

--详细的信息:

# crs_stat -t

使用crsctl check crs命令，如下：

[root@rac1 bin]# ./crsctl check crs

CRS-4638: Oracle High Availability Servicesis online

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Servicesis online

CRS-4533: Event Manager is online

[root@rac1 bin]# ./crsctl check cluster

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Servicesis online

CRS-4533: Event Manager is online

二．停止和启动Resource

在第一节中，看到直接停止集群，相关的Resource 也会被停止。但一些实际情况下，我们操作更多的是对某些资源的操作。具体就是使用SRVCTL 命令

1.1. 官网说明

SRVCTL Command Reference for Oracle Restart

http://docs.oracle.com/cd/E11882_01/server.112/e25494/restart005.htm

查看命令帮助：

Srvclt –h

这个命令显示的结果太长，不好查看，可以进一步的查看帮助：

--使用-h：

[grid@rac1 ~]$ srvctl start -h

The SRVCTL start command starts, OracleClusterware enabled, non-running objects.

Usage: srvctl start database -d<db_unique_name> [-o <start_options>] [-n <node>]

Usage: srvctl start instance -d <db_unique_name>{-n <node_name> [-i <inst_name>] | -i <inst_name_list>} [-o<start_options>]

Usage: srvctl start service -d<db_unique_name> [-s "<service_name_list>" [-n<node_name> | -i <inst_name>] ] [-o <start_options>]

Usage: srvctl start nodeapps [-n <node_name>][-g] [-v]

Usage: srvctl start vip { -n<node_name> | -i <vip_name> } [-v]

Usage: srvctl start gns [-l<log_level>] [-n <node_name>] [-v]

Usage: srvctl start cvu [-n<node_name>]

For detailed help on each command andobject and its options use:

srvctl <command> <object> -h

--或者命令不敲全：

[grid@rac1 ~]$ srvctl database

Usage: srvctl <command><object> [<options>]

For detailed help on each command andobject and its options use:

srvctl <command> -h or

srvctl <command> <object> -h

在11g R2中，默认 oc4j和gsd资源是 disable的；oc4j 是用于WLM 的一个资源, WLM在 11.2.0.2 才可用；gsd是 CRS 用于跟 9i RAC 进行通信的一个模块,是为了向后兼容才保留的，不影响性能；建议不要刪除, 也不要尝试开启他们, 忽略即可。

ora.gsd is OFFLINE by default ifthere is no 9i database in the cluster.

ora.oc4j is OFFLINE in 11.2.0.1 as DatabaseWorkload Management(DBWLM) is unavailable. these can be ignored in11gR2 RAC.

状态检查也可以使用如下命令：

crsctl stat resource –t

或者

crsctl stat resource

1.3.4 综合

1、通过SRVCTL命令来start/stop/check所有的实例:

srvctl start|stop|status database -d<db_name>

2、start/stop指定的实例：

srvctl start|stop|statusinstance -d <db_name> -i <instance_name>

3、列出当前RAC下所有的

srvctl config database -d <db_name>

4、start/stop/check 所有的nodeapps，比如：VIP, GSD, listener, ONS：

srvctl start|stop|status nodeapps -n<node_name>

5、如果你使用ASM，srvctl也可以start/stop ASM实例：

srvctl start|stop asm -n <node_name>[-i <asm_inst_name>] [-o<oracle_home>]

6、可以获取所有的环境信息：

srvctl getenv database -d <db_name> [-i<instance_name>]

7、设置全局环境和变量：

srvctl setenv database -d<db_name> -t LANG=en

8、从OCR中删除已有的数据库：

srvctl remove database -d <db_name>

9、向OCR中添加一个数据库的实例：

srvctl add instance -d <db_name> -i<instance_name> -n <node1>

srvctl add instance -d <db_name> -i<instance_name> -n <node2>

#######################

1. crsctl stop crs/has 关闭整个高可用服务，只能关闭local节点
2. crsctl stop cluster -all 关闭所有节点的clusterware包括资源。OHAS还在.
